To all whom it may concern:

Be it known that I, Prnmr M. Mmmnz, a citizen of the United States, residin in Brooklyn, in the county of of New York, have invented certain new and useful Im rovements in Vehicle- Wheel Pneumatic- 're Rims, of which the followin? is a full, clear and exact description, re erence being had to the accompanying drewin My invention relates to improved means for mounting and quickly securing the tire casings upon demountab e rims and means for quickly mounting and positively securing the rims with the inflated tires thereon upon vehicle wheels, and to means integral with the side of vehicle wheels, participating in locking the same rims upon the respective vehicle wheels.

It is the usual practice to put a' pneumatic tire uponn demountable rim, and there inflate it before mounting the rim on the wheel of, the motor vehicle. In the event the tire is injured or deflated, .the rim is demounted, and replaced b another bearing an inflated tire; and .the detaching of the injured tire from its rim as well as the repairing of the tire, may be postponed.

For use with expansible and non-expcnsiblefibead tires, the rim may be of one integrally flanged endless type. for easily Inountm thereon and from, with a side removable endless flange or clench to hold the tire in position, and the same flange or clench to lockingly enga e the side or the vehicle wheel whereupon dirim with its inflated tire is mountedand held circumferentially locked.

Nearly all dernountable tirecarrying rims now in commercial use are used in connecticn with th'lstening'means which exert at the same point both a radial and lateral nessure upon the rim such as wedge clamps iorced between the is y and rim, or wed rings forced in by clamps), a consider-ah e degree of skill is required for fastening a rim with such devices, because if skill and care arenotcxercised the rim is liable to be bolted on out of a true plane with the wheehand the rim may be drawn oil center in the tightening up of the locking ele- Kings and tate .tion of the doub demountmg there.

ments. If one wedge or clamp is bolted too t1 ht, the demountable rim is usually force out of the plane of the wheel and eccentric with regard to the wheel center at the same time.

The ob'ect of my invention is to obviate these de ects, and rovide a. demountable run havm ori fastening means, and a wheel bo y, 0 such constructions that the rim, associatin' with a side removable endless flange or 0 such to prevent the inflated mounted tire thereon from dislodgment therefrom can be quickly and easily mounted and loched upon the wheel body in a true plane with the wheel, and radially tensioned without danger of undul distorting the rim and throwing the same 0 center by the same means which secure the inflated tire on the mm and similar means provided in the side of the same wheel and run. a

Another ob'ect of my invention is that the means,1o' or clench .withthe tire is mounted on the rim, form an outerslde circumferential contact between the rim and wheel, thus Participating in the forma- -contact line thereb'et'ween to prevent the formation of rust between the contacting surfaces ofthe and wheel.

' f Still another object of my invention is to provide lockin elementary means which shall be devoi ofall wedgingactionfibecause it causes the above mentioned effects.

In a sense the subject matters of this present application may be said to be improvements upon the subject matters disclosed in my pending a plications Serial Numbers 117,565 an 27 ,368, August 29, 1916 and J an. 9, 1919 the former embodgliirllg matter Sertaimng to mounting andhol g on and emounting tire rims from the peripheral surface of vehicle wheelsqi'hile the letter disclosing means for mounting and'holding inflated tires on demountable rims p ..1

the same characteristic features descn e m thepresent aplphcatlon.

Other partic ar advantages of the invention will appear from a detailed descri' tion of my invention in connection with t e drawings forming a partthereof.

The specific ob ect of my invention is to the side removable flange side of the rim after the provide means which shall be applicable to rims and tires of all types, and which shall be provided in the vehicle wheels desired to carry such tires and rims.

In the specific embodiment, in which I have chosen to illustrate my invention, for the purpose of clear.- disclosure, Figure 1 is a perspective view of the demountable rim, without the side removable flange and tire, showing its original lines of construction; Fi re 2 is a-side elevation of the demountab e rim having thereon an inflated tire with the side removable flange in contact with the outer side thereof and locked with the side of the rim; Figure 3 is a perspective view of the demountable flange, showing its original lines of construction; Figure 4' is a cross'section of Figure 2'taken on the line 4-4 as indicated by the arrows Figure 5 is an enlarged perspective view of the wire wheel embodying featuring means for lockingly holding on its outer metallic periphery the demountable rim and side removable flange; Figure 6 is a side elevation of the demountable rim, carrying an inflated tire on its outer periphery and the removable flange locked thereagainst, mounted on the band of the folly of an artillery vehicle Wheel and locked against the side thereof; Figure 7 is a view similar to Fi ure 6, particularly showing the original featuring means of locking the same rim with its inflat/ed tire and removable flange on the mctallic circumference of the wire wheel; Figure 8 is a cross sectional view of Figure 6 taken on the line 8-8 as indicated by the arrows; while F 9 is a view similar to Fi 8 of Figure 7 taken on the-line 99 as indicated by the arrows.

Referring to F re 1, the rim 5 is of an endless cylindrica construction having an inner-side integral circumferential flange or clench 6 and a circumferential tire-seating surface 7 outwardly extendin to and terminating in a series of space radially extending flan 3. The tire-seating surface 7 is provide with the usual opening 8 for receivin the usual inner tube stem, and each of the anges 3 is provided with an outer opening 9 and an inner openin 11.

Referrin to Figure 3, the si e removable flange or e such 2 is of an endless circular construction having an outer circumferential periphery2' and an inner circumferential periphery 2 extending circumferentially to and terminating at intervals in a series of spaced radially extending flanges 4. As shown in Figure 4, the outer circumferential periphery 2 comprises the outerside circumferential flange or clench for preventing the tire 13 from dislodgment from the tire-seating surface 7 of the rim 5, and the series of flanges 4 thereof each correspondingly forming means for engagement with the series of flanges 3, of the rim 5.

Each of the flanges 4 is provided with an outer openin 10 and an mner opening 12, the former aligning with the opening 9 and the latter g with the opening 11 of each of the flanges of the rim.

To lockingly hold the tire 13, with the inner tube stem 16 through the opening 8, on the tire-seating 7 of the rim 5, the endless circular flan or clench, shown in Figure 3 and herein fore described, is removably mated with the side 1 of the rim so that the flanges 4 align with the flanges 3 of the flange or clench and rim, respectively, and the outer circumferential periphery 2, forming a tiregi portion, engages the outer bead and si e of t e tire 13, thus mutually forming a circnmferentially tire-seating channel between the integral flange or clench- 6 of the rim and inner side of the respective periphery 2, as substantially shown in Figure 4. A series of bolts 18 each, pen ticularly'being provided with a square head which may conveniently extend to and terminate in a suitable obtuse or blunt portion, is removably secured in the corresponding openings 9 and 10 of the flanges 3 and flanges 4 of the rim and flange or clench, respectively, to securely draw the respective flanges 3 and 4 together and the rim firmly and creeplessly ositioned in relation with the res ective ange or clench 2, and to form, as ereinbefore described, a circumferential tire-seating channel; aseries of nuts 21 each threudedlyi secured to the threaded end of each of t 6 bolts 18 to lockingly hold the same in position, with their respective square heads in relation with inner surface of each of the flanges 3, to finally provide an inflated iiire on the rim as ready for use, as shown in H in 'igures 5, 6 and 7.

Inthe drawin I have illustrated an artillery wheel an a wire wheel each comprising a hub, spokes, and folly or fixed rim of the kind in most common use, the particular conformation of which is not im portant so far as the present invention is concerned, with the exception of the outer side of the tire-seating perlphery of the wire wheel hereinafter described and illustrated in Figure 5.

As shown, the wire wheel is provided with an endless cylindrical periphery 28 having an inner-side integral circumferential flange or clench 29'- and a circumferential tireseating surface 31 outwardly extending to and terminating in a series of spaced radially extending flanges 29. The tire-seating surface 31 is provided with the usual stemreceiving opening 30, and each of the flanges 29 is provided with an opening 32.

To demountably position the demountable rim 6, having thereon the inflated tire 13, the ordinary flap 14 and inner tube 15, with the inner-tube stem 16 through the usual re 2, on the wheels, respectively shown opening in the telly 23 andbund 24, as respectively shown in Fi assembled rim tire and elige particularly ustrsted in cumferentially mounted on e band 24 of the felly 23, the inner side of the rim seating on the inner-side inte e1 flange 25 and the outer side thereof simi arly relating with the outer circumferential portion 26 of the band, having interposed circumferentially the squareheads of the series of bolts 18 to form a firm spacing means therebetween, as shown at 27. e eries of spaced radiall extend flanges 3 and 4 of the rim and ange or ench 2, res ectivel engage the outer side of the fel y 23, t e corresponding inner openings 1 and 12 thereof each passi a bolt 19 ordinarily situated in the side oft e telly 28, as shown in Figure 8, to he threudedly locked with a nut 21" which, in turn, forces the contactin rtion of the f! e inwardly of the w e and the mounii efii assembled rim and tire circumferor clen as 2, is carentielly locked on the wheel, as shown in- Figurefi, to be ready for use.

To similarly mount the assembled rim,

inflated tire and ide removable flange shown in Figure 2, on the rim-seatin surface 28 of the wire wheel, shown in igure 5, the inner aid; of ]the rim iisflcircungge railitiall itione ont e integra ange' ereo 5% the inner-tube stem 16 through the opening 30, and the lockingly spaced square heads of the bolts 18 are cimumferentially interposed between the outer sides of the respective rim end portion 31 of the wheel. The series of spaced radially extending flanges 3 and 4 of the rim and flange or clench 2, respectively, enge the flanges 29 of the wheel, the correspon in inner openings l1 and 12 of the-run an flange 2, respectively, align with the openings 82 in the sideof the flanges 29 together to pass a bolt or suitable threaded memberQO to be threadedly locked with a nut 22 which, in

turn, forces the contacting ortion of the flanges inwardly of the w eel, and the mounted assemb ed rim and tirecircumferentially locked on the wheel, as shown in Figure 7, to be read for use.

Throughout the, rawings the demountable rim and flange are shown in cross section to be of the straight fi pe but er type they emlay be constructed of the c on Tothe end that my invention in its greferred form may he quickly understoo I shall here explain that a c idea embodied therein is that of clamping the rim in double-line, the subjeotmatter of which is exglained fully in'the application Serial Num er 117,565, with. the peri hery of the wheel, at it opposite sides, an side relative to the existhereof. e term double-line contact means the relatively wide 4 and 6 the bl hief inventive or broad line of contact afiorded by the doue circumferential contact of the mar side of the run against the flange portion 25 of the hand Beef the artillery wheel, or fla portion 29 of the wire wheel 28, and e square heads of the bolts 18 spacingly interposed between the outer side of the respective run and felly band 24 of the artillery wheel, or the outer portion 31 of the wire wheel, the bolts 18 being retained by the openings 9 and 10 of the flangesof the reepective rim and removable side e which are thereby bound together, as herelnbefore described. By so suppo the rim at its double contact ints provide the rim and tire with an i eally firm support, coextensive with the circumference of the wheel, but so positive as to avoid all danger of the rusting together of the parts to an extent which won d prevent the easy demounting of the rim from the wheel. A coincident inventive idea is that of providing the rim and removable side simultaneously serve as a positive binder for the outer side of the rim and removable fl together to form a tire-seat chan nel etween their respective facing si es, and the assembled rim with its-inflated tire se. cured on the wheel by locking of the rim and with the'side of t e wheel, thus participating in the formationof the double-line contact, hereinbefore described. Another coincident inventive idea is that of positive! supporting the arc of the rim in the doub e-line contact and thereb preventing or avoidin the distortion of tlie rim, which would at erwise throw the rim out of true and tend to prevent'circular mounting of the rim on the wheel.

From the foregoing description, taken, in connection with the accom'pan ings, it will be alpparent that I 'rovide an exceedingly eimp e and highly e cient combination for quickly mounting the tire on the rim and uickly connecting and disconnecting the emountable rim to and from the wheel body. By means of the construction herein shown, the rim must necessarily tion;' By means of the lateral fastening devices employed in connection with the side of the wheel havin .s sci lyinterosed the square head; ofth e bolts la p and wheel, the rimwith the tire i rigidly and properly connected to the wheel body,

etween the rim and, owing to*th'e formed outer-side contact" line, it is practically, impossible todistort the rim during its use on the wheel on the road.

I know that numerous wheel bodies and clemountable rims therefor are now, together with attachments for wedging the rim from the wheel body in a radia and outward direction, in common use for ositively moving the rim axially and simu taneously causing radial pressure and peripheral tension on the rim. I eliminate entirely wedging devices; all arts of m rim res and to the ressure on incs paral el with tie axis and ateral with the wheel body. And the inte ral arts of the rim contacting with the side 0 the wheelbody move laterally of the wheel and are secured in a neutral plane to circumferentially form the double-line cont-act'between the rim and wheel.

I believe myself to be the first to have so constructed a wheel body, a demountable rim and a side removable flange, that the rim together with'the flange, holding an inflated tire on the channel thereof, is removabl secured on the wheel body, without any we ging means, by inte "a1 means embodied in the rim, flange an wheel body, thus serving two urposes, one of which secures the tire on t e mm; the other, independent of the first, locks the rim on the wheel. And I am the first to have provided (a) a demountable rim having an integral tireengaging rtion and a circumferential smooth sur ace for contacting with the periphery of the outer head of a tire, which surface extending to and terminating in a series of spaced radially extending flanges to be mated with (b) an endless side removable flange havin a circumferential outer periphery comprising a tire-engaging portion and an inner periphery comprisin a rim-side engaging portion radially extencf in to and terminating in a series of spaced ra ially extending flanges, and (a) means, independent of the last said means, by which the rim is mated with the flan e to carry an inflated tire irrespective of the wheel body. And it is obvious by such construction that, by the combined integral means o f the rim, fia e and wheel body, the assembled rim wit the tire is demountably positioned on the wheel, de nding upon the same means which bind tie side of the rim with the flange to carry the tire, to be locked together.

It is to be understood that if desired or necessary to have the outer side of the rim radially extended to or formed a circularly integral radial flange, the rim may be constructed with a side integral flange, as particularly shown at the circularly dotted line by the arrow 'A, and, similarly, the same flange may be formed with the inner periphery of the side removable flange, as particularly shown by the circularly dotted line and arrow B.

To those who are skilled in the art, it will be apparent that by means of the structure herein articularly disclosed, I accom plish the fulfillment of all the objects and re uirements herein set forth.

hile I have illustrated and described my invention in accordance with the draw ings, I desire it to be understood that the details of construction may be materially varied, and that many changes, modifications and substitutions may be made in the demountable rim herein illustrated, provided the means are employed without departing from the spirit and scope of my invention set forth in the claims.

Having thus described my invention, I desire to secure the same by Letters Patent in the following 1, An endless cylindrical demountable rim havin an inner-side integral circumferential ange and a circumferential smooth surface outwardly extending to and terminating in a series of spaced radially extending flanges, an outer opening and an inner opening in each of sai flanges, an endless annular flange having an outer circumferential periphery and an inner circumferential periphery circumferentially extending to and terminatin in a series of spaced radially extending anges, an outer o ning and an inner opening in each of said anges, the said latter fla. with their openings corres onding to an aligning with the former an es with their openin the said annular ange being mated wit the outer side of the rim to register the series of flanges and openings thereof with the series of flanges and o enings of the rim, a. series of square-heade bolts each having a blunt portion and passed outwardly through the said outer openings to secure the registered parts together, and a series of nuts each secured to the threaded portion of each of said bolts to lock the registered gether.
